Real Places Around the World People Aren't Allowed to Visit Anymore

Mariana Trench, Pacific Ocean

If there’s one lesson we should take from our ancestors, it’s that the ocean isn’t just beautiful—it’s also cruel and unforgiving. Throughout history, the ocean has claimed countless lives, serving as a grave for many. So, it’s no surprise that it’s packed with zones too dangerous to explore, whether by foot or by boat. Take the Mariana Trench, for example. As the deepest part of the ocean ever discovered, it’s a place of mystery and peril

Bubbles of carbon dioxide and sulfur occasionally rise to the surface, a haunting reminder of its inhospitable nature. Why would anyone venture into such a no-go zone? The extreme pressure and complete darkness make it nearly impossible for humans to survive there. Add to that the toxic chemicals and lack of oxygen, and it’s clear why this underwater abyss remains one of the most treacherous places on Earth. The ocean may captivate us, but it demands respect—and caution.
